Have you ever wished you had an inflatable lover?
Of course you have.
Have you ever wished your inflatable lover was snake-shaped?
Naturally!

Balloon Snake

This is probably one of my weirder stories, as it involves a living inflatable. It's been a long long time in the 'making' and mostly grew out of a random idea that became a couple images, then a sequence, and eventually a story.
It's probably going to be a little niche; I have no idea how much people will actually like a balloon snake story. But, if you're into that sort of thing, check it out!

Tag "female:snake" means - A FEMALE IS BEING SEXED BY A SNAKE.
